摘要:	摘要： CAC (Call Admission Control) plays a significant role in providing QoS (Quality of Service) in mobile wireless networks. In addition to much research that focuses on modified Mobile IP to get better efficient handover performance, CAC should be introduced to Mobile IP-based network to guarantee the QoS for users. In this paper, we propose a CAC scheme which incorporates multiple traffic types and adjusts the admission threshold dynamically using fuzzy control logic to achieve better usage of resources. The method can provide QoS in Mobile IPv6 networks with few modifications on MAP (Mobility Anchor Point) functionality and slight change in BU (Binding Update) message formats. According to the simulation results, the proposed scheme presents good performance of voice and video traffic at the expenses of poor performance on data traffic. It is evident that these CAC schemes can reduce the probability of the handoff dropping and the cell overload and limit the probability of the new call blocking. 出版者： Cairo, Egypt: Hindawi Puplishing Corporation 出版日期： 2012-01-01 出處： Journal of computer networks and communications, 2012-01, Vol.2012 (2012), p.1-10 資源來源： Publicly available content database 版權： Copyright © 2012 Jung-Shyr Wu et al. 識別號： ISSN: 2090-7141 識別號： ISSN: 2090-715X 識別號： EISSN: 2090-715X 識別號： DOI: 10.1155/2012/109685
